Evolution of the flame-front movement in burner stabilized turbulent premixed flames in a reaction sheet regime has been examined. At the almost entire position except the vicinity of the burner axis in the turbulent flame brush, flame fronts pass the stationary measuring position alternately in the burnt-to-unburnt then unburnt-to-burnt directions. There is an influence of the direction of flame front passage. When the flame front passes the measuring position in the burnt-to-unburnt direction, it moves away from the burner axis, but when the flame front passes in the unburnt-to-burnt direction, it moves toward the burner axis. In the former direction, the flame-front movement is follow the gas flow, while in the latter direction, the flame-front movement is against the gas flow.
